Renault has confirmed it will power Toro Rosso from 2014 onwards when the new V6 turbo engine regulations come into force.

Toro Rosso, currently powered by Ferrari, revealed it was in talks with Renault at the start of the season so the news comes as little surprise, but it does come at a time when several engine contracts are up in the air for next season. The deal makes sense as both Red Bull-owned teams will now be powered by the same engines.

"While it is logical we would discuss supplying Toro Rosso based on our partnership with Infiniti Red Bull Racing, it was not a foregone conclusion," Renault Sport F1 president Jean-Michel Jalinier said. "We carefully considered what is best for all parties before concluding the agreement. Toro Rosso is a well-run, established team, with strong personnel and facilities giving the team the potential to be a regular points contender.

"Renault remains involved in F1 to win and demonstrate the excellence of its products. To achieve our aims we need to have teams functioning at the highest level, which is why we are delighted to sign with Toro Rosso.

"Off track it will also enable us to further promote the association with the Red Bull brand to our customers worldwide. We look forward to creating a long and multi-level relationship with Toro Rosso, just as we have with Infiniti Red Bull Racing."

Franz Tost, Scuderia Toro Rosso team principal, added: "We are very pleased to have reached an agreement to use Renault power units from the 2014 season onwards, when the new regulations will present interesting challenges. It is particularly important that we have managed to finalise our plans early, so that we can be as well prepared as possible for next year. While looking forward to working with Renault, I would also like to thank Ferrari, our engine supplier since 2007. They have provided us with an extremely effective and reliable engine and an excellent service."

Red Bull will continue as Renault's "development partner", with Christian Horner saying: "Strategically for Red Bull and Renault, it makes perfect sense for Scuderia Toro Rosso to use the same power unit as Infiniti Red Bull Racing from the 2014 season, which enables synergies between Red Bull and Renault to continue to grow."

The news comes as Williams is expected to confirm a switch from Renault to Mercedes power next year. It means Renault has three confirmed contracts under the new regulations with Red Bull, Toro Rosso and Caterham. Lotus has yet to confirm if it will stay with the French manufacturer.
